JOHN HENRY REEDER, OF GADDO, OKLAHOMA.

VISE.

To all whom it may concern:

Be it known that 1, JOHN HENRY REEDER, a citizen of the United States,residing at Caddo, in the county of Bryan and State of Oklahoma, haveinvented certain new and useful Improvements in Vises; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to Vises, and more particularly to those whichhave a sliding jaw moved by a cam; and the object of the same is toproduce a vise of this type for use by the blacksmith, wood-worker, orperhaps saddler, and so constructed that its reach may be contracted orexpanded to fit v the work to be grasped by it and its movable jaw maybe thrown into active engagement with said work by depression of astirrup. This and other objects are accomplished by the constructionhereinafter more fully described and claimed, and as shown in thedrawings wherein Figure 1 is a side elevation of the vise. Fig. 2 is afront elevation of the same. Fig. 3 is a longitudinal section of thevise proper showing the beam in side elevation. Fig. 4 is a horizontalsection taken on the line 4-4 of Fig. 3. Fig. 5 is a transverse sectiontaken on the line 55 of Fig. 1. Fig. 6 is a detail perspective view ofthe loop and its dog. Fig. 7 is a detail vertical section through therod and dog showing clearly the manner in which the rod is locked.

What may be called the fixed jaw in this vise is mounted upon a turretwhich comprises a base 5 having ears 6 screwed upon the workbench in theusual manner, a standaid 7 having an enlarged and preferably round lowerend or turn table 8 centrally pivoted upon the base by means of a pin 9as seen in Fig. 3, and the upper end of the standard is formed into thejaw 10 proper. Just below the latter through the standard is formed arectangular opening of a size at its upper part to admit the freepassage of the beam 11 which has a toothed rack 12 along its lower edge.Engaging the teeth of this rack is a spring-actuated pawl 13 pivoted inthe reduced lower part of the opening below the beam, and the rear endof this pawl is adapted to be raised by depressing the outer end of apivoted trigger 14 in am anner best seen in dotted lines in Fig. 5. Thistrigger is pivoted to the face of Specification of Letters Patent.

the fixed jaw and swings in a plane at right angles to the length of therack, whereas the pawl 13 is pivoted within the opening in the standardor fixed jaw and swings in a longitudinal plane extendlng through saidrack bar. It follows that when the trigger end of the standard, and thebeam is adjustable through the latter at will.

Pivoted to the outer end of the beam at 15 is a cam 16 whose body isforked for that purpose, and the active face of the cam lies against theback of the movable jaw 17 which latter is thereby pressed toward thefixed jaw 10 when the cam is depressed.

These members are connected by a coiled spring 19 as best seen 111 Fig.3, so that as the cam rises 1t retracts the movable aw and moves it awayfrom the fixed jaw. The

outer end of the cam carries an arm 18, and

it is obvious that when this arm is depressed the cam will be turnedupon its pivot 15 and the movable jaw will be pressed toward the fixedjaw so as to clamp the work between them.

\Vhen this improved device is intended to be operated by the foot of theworkman I employ a rod 20 loosely attached to the outer end of the arm18 and having at its lower end some foot mechanism such as a stirrup 21into which the foot of the workman may be inserted. This rod passesloosely through the loop 22 best seen in Fig. 3, and the loop may beattached to the floor by means of a bracket or suitable means 23.Through one side of the loop passes loosely a dog 24 having an eye 25 atits inner end which loosely embraces the rod 20 when the dog standshorizontal, but is so disposed that when this dog is tilted upwardslightly as shown in dotted lines in Figs. 1 and 2, the eye is canted tosuch an extent that it bites the rod and prevents further movement ofthe latter through the loop. However, when the outer tion of the eye onthe rod ceases and the latter is again permitted to rise. It resultsfrom this construction thatwhen the workman places his foot within thestirrup and presses downward thereon, the rod is drawn downward throughthe loop and through the eye in the dog, but as soon as he releasespressure and the tendency of the rod is to rise, in doing so it cantsthe dog in place and causes its eye to bite the rod so that the lattercan rise no farther. When it is desired that the rod shall rise, the dogis tripped by any suitable means as by the operators hand or foot.

Thus it will be seen that I have produced a vise whose standard ismounted on a turret on the work bench so that it may be revolvedthereover to bring the outer end of the beam to a point beyond the edgeof the bench when the foot mechanism is to be attached although when thelatter is detached the vise may be swung around to any position desiredby the workman. Having inserted his work between the jaws and across thebeam, he pushes the latter and the movable jaw with it toward the fixedjaw so that the beam and ratchet teeth slide through the opening andover the pawl in a manner which will be clear, then by depressing thearm 18 (either manually or through the foot mechanism) the cam is causedto move the movable jaw toward the fixed jaw to clamp the work firmlyand hold it there until pressure is removed.

All parts of this device are of the desired sizes, shapes, proportionsand materials, ex-

cepting that of course I prefer metal for the latter; and considerablechange may be made in the details of construction without departing fromthe essential principle of my invention.

What is claimed as new is:

1. In a vise, the combination with an upright standard pivoted upon abase and having through it an opening which is rectangular at the upperportion and reduced in width at the lower portion, the upper end of saidstandard forming the fixed jaw, a beam slidable through the larger partof said opening and having teeth on its under side, a movable jawmounted slidably upon said beam, and means for setting it thereon; of aspring-actuated pawl pivoted in the smaller portion of said opening withits tip normally engaging said teeth and its other end projecting out ofsuch opening, and a rectangular trigger pivoted to the face of thestandard at one side of the lower end of said opening and moving in aplane at right angles to that in which said pawl moves, as and for thepurpose set forth.

2. In a vise, the combination with an upright standard carrying a fixedjaw and having an opening through it, a beam passing through saidopening, means for adjusting its position therein, a movable jawslidably mounted on said beam, and a cam pivoted to the outer end of thebeam behind the movable jaw and having an arm; of a rod hanging from theouter end of the arm and having foot-mechanism at its lower end, a fixedloop through which the rod slides loosely, and a dog pivoted through oneside of the loop and having an eye loosely engaging said rod and adaptedwhen canted to bite the rod and prevent upward movement thereof.

3. In a vise, the combination with an up right standard carrying a fixedjaw and having an opening through it, a beam passing through saidopening, means for adjusting its position therein, a movable jawslidably mounted on said beam, and a cam pivoted to the outer end of thebeam behind the movable jaw and having an arm; of a rod hanging from theouter end of said arm and having foot mechanism at its lower end; a loopthrough which said rod moves freely, a bracket connecting the loop withthe fioor, and a dog pivoted through one side of the loop and having aneye loosely engaging said rod and adapted when canted to bite the rodand prevent upward move ment thereof.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
